    Sure thing! @DanTheMan827 and I are actually working towards the same (or at least substantially similar) goals.

    The root of my project is this thing I'm calling the AmiiBuddy, which I have a short demo of here.

    I have all of the basics working with a rewritable magic NTag215 card, but the idea of being able to have the device communicate the nfc info over a longer distance seems too great to not at least explore. :)

    Swapping out for another FT232R did the trick! YAY! Thanks everyone.

    At least on the FT232R's I have, D28 goes to RX, and D29 goes to TX.

    Well, if I weren't planning on trying to do some bluetooth stuff, that would be viable, however I have an aversion to "debugging via rumor", so getting bluetooth connectivity working without active terminal looks pretty dark... :)

    That's a good point about the "context" of TX/RX -- it's all relative.

    Well, I got a little closer messing with it last night...

    First off -- this has all been with the battery removed. I was like "Oh? I can test this without spending battery at all? Yes please." :D

    Now... what I got working was: I could receive data in the puck FROM the terminal.

    I could not, however, get output from the puck to show up on the terminal. At all.

    I assumed maybe I had a bad soldering job or something, but when I flipped the TX/RX pin connections and in the .setup() call... I could receive terminal input!

    So... both of the connections seem solid.

    Then I noticed on the FT232R, it's got TX and RX lights that fire up when data transmits over the respective channel.

    Nothing I did could get the lights to blink when sending output to the console. Serial1.print(), Serial1.println()... none of it seemed to trigger actual outgoing data.

    I believe I tested swaping the TX/RX pins as well.

    Tonight I'll grab a different FT232R and do some more testing.

    I'm using the defaults when I pick the device in Serial2, I think it's something like 9600,8,N,1 ? I can check tonight to be sure, but I know I was using at least 9600 baud, 8 bits, and no parity.

    I'll have to try the first script set you gave me later tonight as well, but I did try Serial1.println("blah") and got nothing.

    Shouldn't

    Serial1.setup(9600,{rx:D29,tx:D28});
    

    be

    Serial1.setup(9600,{rx:D28,tx:D29});
    

    ?

    Yeah, this made me wonder..

    Firstly, I am doing this all without a battery in.

    So then I plug it all in to the USB-TTL (as described above), and then plug the USB-TTL in to the computer.

    When that didn't work, I tried pulling the connection for 3V and plugging it back in.

    That didn't work.

    I tried similar with GND, and that didn't work either.

    GND is connected to GND...

    I'm using this https://www.amazon.com/gp/product/B07XF2­SLQ1.

    TTL's pins are: DTR, RX, TX, VSS, CTS, GND

    Puck -> FT232R connections are:
    V3 -> VCC (set at V3.3 and not V5)
    GND -> GND
    D28 -> RX
    D29 -> TX

    (edit: changed pin TS to CTS -- misread it)

    Hey there!

    So I have a Puck.js v2, and I followed https://www.espruino.com/Puck.js#serial-­console to hook it up to an FT232R -- Pin 28 to RX, Pin 29 to TX, set VCC to 3.3V, ran to 3v, and ground to ground.

    The puck fires up, but refuses to talk via Serial1.

    If I go in to the IDE via BT, Serial1.available() reports 0.

    Serial1.setConsole(true) just makes it not respond via BT any more, and doesn't get the wired serial side working.

    Any ideas?
